The primary object is toprovide a simple structure of a novelcharacter that will deliver oil in'a-suflicient quantity' into the air stream, while thepres'su-re is on the hose or conduit, andwill promptlystopthe delivery upon the reduction of the" pressure, when the supply o'fair is cutoff. v

Another stem 24 is threaded transversely through-the conduit 7 in line with the opening throughthe nipple l4, and is provided with a longitudinal bore 25 opening through its upper end, but ter-rnb nating. short of its lower end, said lowerend of the stem projecting into the passageway 8.

A transverse port 26 in communication with.

the lower end of the bore 25 opens into the passageway 8, but faces the inlet end 11 0f said passageway. 1 i c In operation, assuming the reservoir 1-0 of this air will find its way through the port 26 and bore'25, thereby creatingpressure u-ponthe oil and-causing a smallstream to be projected through the-port21into theair stream, This 'pressure in the reservoir 10 will be slightly in excess 'ot'the pressureof; the air stream by reason of the fact that the port 1 26' faces said air stream-while" the port 21 opens in the direction'of the air stream, and it hasibeen found that-the difference is sufficient-to insure'the expulsion of the oil" from the bottom of the reservoir. As soon' as theair is cut off andpressure is reduced in the-passageway 8, the pressure inithe resenvoir will be correspondingly reduced and thus the outflow of oilinto the'passagewayi autoe matically stops. .v to

'A'n outercasing '6? is illuse trated, through which extends a conduit '75 for; the; passage of air or other motive; fluid, the passagewaybeing illuStratedat- S said passageway has an inlet nipple 11 and an outlet nipple 12. shown at 10 and has a fillingnipple 14 at one side closed by a plug 15 A central nipple 16 affords access for the introduction of a double stem i8 that is threaded into the upper portion of the conduit 7 and extends across said conduit into the lower end of the reservoir 10*. This conduit has a bore 20 in its lower portion that is in communication with the passageway 8 through a port 21 that opens in the direction of the outlet nipple 12 of said passageway. The upper end of this stem 18 hasa eonduit 25 provided at its lower end with a transverse port 26 that opens into the passageway 8 towards the "inlet nipple 11 The passageway 25 furthermore has a transverse port 27 at its upper end which port is in communication with transverse ports 28 that open into the upper portion of the reservoir. The ports 28 are preferably formed by drilling a transverse hole through the upper end of the conduit 7*, this port being made possible by drilling through the side of the casing 6 as shown at 29 in Figure land the hole 29 being closed by a plug 30 Obviously the operation of thisistructure is precisely the same as that bodiment;

From the foregoing, it is thoughtthat the construction, operation and many advantages of the herein described invention will be apparentto those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction, may be'resorted to without departing from of the first, em-

the spirit or sacrificing any of the advantages of the invention.
